Hi,

I just wanted to say, it's funny how I did the *EXACT* same thing only **a few
days ago**:

Not counting the braces, the actual code is just 4 lines for the compile-time
version, and 5 lines for the run-time version. The page above only has a link to
one of these; both of the versions are here:

Pretty short, eh? I doubt that it can get any shorter than that code. :) Feel free
to use my version inside the library. ("I hereby release the code to the public
domain," to cover the legal stuff.)
